yex.parse.ListSource

yex.parse.ListSource(contents, name=None)

Bases: yex.parse.source.Source

A source based on a list. Generally this is a list of strings, although you can use anything you want the tokeniser to find.

Multi-character strings are split into their component characters; any other entries are left as-is. For example, if you passed in

['a', 177, 'b', 'fred', 'c']

the tokeniser would receive

• "a"
• 177
• "b"
• "f"
• "r"
• "e"
• "d"
• "c"

Attributes:

Name	Type	Description
contents	typing.List[typing.Any]	the list.
